revolution in the 1970s.

The Apple II microcomputer, introduced in 1977, was a hit with home users. In 1983, Apple introduced the first commercial personal computer to use a graphical user interface (GUI), the Lisa, influenced in part by the Xerox Alto. In 1984,
Apple introduced the revolutionary Macintosh. The Macintosh (commonly called the "Mac") was the first successful commercial implementation of a GUI. Similar GUIs are now used in all major computer operating systems from Windows XP to
Unix-like systems using GUIs based on the X Window System such as CDE, KDE, and GNOME.
